Q. The network adapter shown for my Microsoft Failover Cluster Virtual Adapter (NetFT) shows as 100Mbps, but all my networks are 1Gbps or faster. Why does it show 100Mbps?

A. All adapters must have a network speed, and for NetFT Microsoft choose 100Mbps. This is an arbitrary value and doesn't actually limit the speed of data sent via NetFT to 100Mbps. This can be seen in the example used in the previous FAQ, which has a data copy via NetFT. In that example, the link speed goes off the chart but on the adapter NetFT is bound to goes to 50 percent utilization, or 500Mbps.

The lesson here is not to worry about it. In the release candidate and final version of Windows Server 2008 R2, the NetFT adapter speed will be changed from 100Mbps to 10Gbps.
